I’m dealing with lifer failure on 2020 ram. I always kept MDS off as well. And now I’m learning that when MDS is off, certain parts of the engine do not get lubed properly. There is several youtube videos on it. I’m not a master mechanic but there is no excuse for a three year old truck that’s been properly maintained to have these sort of engine failures and then only to have the dealership break one off in you as well.
I had to have my transmission replaced in my 2020 at 12k mikes. And now lifter issues/ cam issues.
Seems like American made equals Rags nowadays. And I hate it because the truck looks so good and is a beast when it’s not in the repair shop. But my next purchase is probably gonna be foreign. Maybe a new tundra, or Corolla. I hear they are good for 300k
